Why she might be annoying

Jill has been accused of being unfeeling and cold toward her younger sister.
They were initially reported to be feuding when Jill was found to not be following Jess on Twitter.
Reports surfaced thereafter that Jessa was allegedly jealous that Jill and Derick held their wedding before her own wedding to Ben.
Jessa was allegedly further upset that the widespread coverage of Jill's wedding was going to overshadow her own wedding scheduled for November 2014.
Further squabbling was reported between the two over Jill being gifted with a $1.5 million house from their father while Jessa was gifted with a house previously occupied by Josh and his wife Anna (who ever heard of a hand-me-down wedding present?)
The two tried to downplay rumors of a feud by releasing Instagram photos of themselves happily dining with both of their husbands in attendance, but rumors continued to spread, specifically ones claiming that Jessa was jealous of Jill's getting pregnant first.
The tabloid reports were so relentless that one inside source was reported as saying 'all that [Jill] wants for Christmas is a positive pregnancy test' (Papa Duggar allegedly claimed Jill was given the bigger house because she would 'have a lot of babies' where more rooms were needed).
Some claimed that they appeared rehearsed in their highly rated interview with Megyn Kelly. Others claimed they were covering for Josh's behavior either out of a desire to maintain their celebrity status or due to the psychological conditioning of their Baptist upbringing.

Why she might not be annoying

They are polite and well-behaved young women.
Gay Rights activist Dan Savage subjected them to the obscene hashtag, #FuckFirst, to mock their stance on abstinence/gay marriage.
They expressed their intention to use their newfound status to advocate for other child molestation victims.
They were screwed over via the unethical leak of private, legally protected counseling documents.
Jessa went on a good-will mission overseas in Central America, along with her husband and newborn baby.
They criticized Josh Duggar after revelations surfaced about his infidelities and Ashley Madison account (albeit very gently).
While their 'Kelly File' interview didn't score the ratings of their parents' interview, it was easily the highest-rated Friday night news segment (and the highest rated Friday-night segment in the show's history).
They were in talks to do a spinoff about life after their family's scandal, but their dad put his foot down when he found out that he wouldn't be involved.
Even those critical of Josh or his parents' actions generally sympathized with the trauma the two experienced by having their sexual abuse experiences rehashed so publicly.
After several (alleged) petty arguments, they were probably brought closer together by having been made to recount their childhood trauma on national television.
